To all whom it may concern f Be it knownthat I, ROBERT (W. RUTH, a

citizen of the United States, and resident of Belle Vernon, in thecounty of Fayette,

and Stateof Pennsylvania, have invented a new and useful Improvement inSwaging- Machines, and I do hereby declare the followin to be a fullclear'and exact descri .2: a V 7 T eating dies, whose operation isattended with a great noise and severe yjarring action, which is notonly nerve-racking to those 1n the vlcinity of such a machine, but isvery severe on the wear and teardue to this jolti-ng and jarring actionof-theparts. V t

In the accompanying drawings,Figure 1 is a plan view of my improvedmachine; Fig. 2 is a section on the line 2-2, Fig. 1; Fig. 3 is an endview; Fig. 4' is a longitudinal section of the w'abbler and thecross-head'; and Fig. 5 isasection on the line 55 Fig. a j i In thedrawings, the numeral 2 designates a suitable bedplate in which thedriving mechanism is mounted. A motor 3 has the pinion 4 on its armatureshaft meshing with the gear-wheel 5 on the stub-shaft6 mounted insuitable bearings A suitablezclutch 8, keyed on theshaft 8, is operatedbythe lever 9 for moving said clutch into and out of engagement with thestub-shaft .6.

The counter-shaft 1 0 is driven by the worm 11, 'onlthe shaft 8?,meshingwiththe w0r1n-wheell2 mounted on said shaft 10. The shaft 10 ismounted in suitable bearings13..-

Mounted on the shaft 10is the cam-disks 14 with cams 15 formed on itsperiphery. The cams l5 gradually increase in size, reaching a maximum at16 to provide for the gradually increased movementa-of the swaging dies,as more. fully hereinafter set forth.

The periphery of the cam-disk 14 engages the idle roller 17 mounted onthe rocker-arm 18 which is pivoted at 19 to the support 20. Thisrocker-arm18 has the seat 21 to receive the wabbler 22.

Application filed January 17, 19 18. Serial No. 212,183.

This wabbler 22 fits in the recess 23 formed in the end of the plungerportion 24 of the cross-head 25. Ths cross-head 25 is of the spider formhaving four arms, which arms pass through openings 26 formed in theguide-frame 27. The guide-frame 27 has the flange 28, the bolts 29passing through said flange are connected to the bearings 13. Theopposite end of said guideframe 27 is connected by the bolts 30 to thestationary frame 31. In this manner, the guide-frame 27 is securely heldin place and acts asa guide for the cross-head 25 and the plungerportion 24.

l The cross-head 25 is connected up by bolts 32 to the togglering 33.

Mounted on the bolts 32 and interposed between the cross-head 25 and thestationary frame 31 are the springs 34.

The guide-rods 35 connect the stationary frame 31 with thestationary-frame 36 and said guide-rods pass through openings in thetoggle-ring 33, and form guides for said tog gle-ring' as it moves backand forth in the manner more fully hereinafter set forth.

The toggle-ring 33 has the blocks 37 fitting in seats 38 and held inplace by the bolts 39. Adjusting screws 40 are provided for adjustingthe position of the blocks 37. These blocks 37 are arranged radiallyaround the toggle-ring 33, and toggles 41 fit into seats 42 in saidblocks 37, and the other ends of said toggle engage seats 43 in theswaging-jaws44. V

These jaws 44 are pivoted at their inner ends by the pins 45 to thebrackets 46 secured to the stationary frame 31 by bolts 47. Adj ustingscrews 48 are provided for adjusting the position of the brackets 46.

Springs 49 on the bolts 50 are interposed between thenuts 51 on saidbolts and the brackets 46, the inner ends of said bolts being securedinto the 'swagingijaws 44. These springs act to return the jaws tonormal position after they havebeen advanced in the swaging operation.

Suitable swaging-dies 52 are bolted or otherwise secured to theswaging-jaws 44, said swaging-dies varying in shape accord ing to theshape to be given to the article to be swaged.

The operation of my improved swaging machine is as follows:

Rotary movement is imparted to the cam disk 14 by throwing the clutch 8into driving engagement with the power-shaft, and

as said cam-disk rotates, the cams 15 engage in succession the roller 17and through the rocker-arm 18 impart a longitudinal movement to thecross-head 25 and likewise to the toggle-ring 33 connected thereto. TheY article to be swaged, having been properly heated,and let it besupposed that in this case the article consists of a short tubularsection which is to be swaged by the dies 52,i-is inserted between thedies, andas the toggle-ring 33 is advanced by the; movement ofthecross-head 25, the toggles d1 acting on the swaging-jaws 44 will movesaid aws inwardly and the swaging dies will be forced against thearticleheld in position therein. As stated above, the cams 15. of thecamdisk 14 gradually increasein size so that the inward movement of theswaging-jaws is slightly greater each time said toggle-ring advances,and the swaging action takes place gradually by a squeezing or apressingaction until-the maximum cam 16 engages the roller 17 and the greatestmovement is imparted to the swaging-rjaws whenthe swaging action iscompleted. 7 T o 'By this means for causing successively progressiveradial movement to the dies, the swaging is accomplished by a gradualsqueezing or pressing action, and the swa ing takes place without theawful din and clatter which is present in the swaging inachinesordinarily' employed where-there is a quick reciprocating action of theswagingdies and furthermore, by my improved ma-. chine, wear and tear onthe parts is reduced to a minimumdue to the fact that there is none ofthe chattering or racking action such as is present in machines ofthejrecip rocating type.

It will be apparent that the adjustments may be quickly made for takingcare of. different sized articles to be swvaged for the amount ofswaging to be donejto any article, and that the dies may be readilychanged to impart diiferent sizes, shapes ortapers to the articles tobeswaged.

What I claim is: i

1. In a swaging-machine, the combination,

of radially-arranged movable swaging-dies,
